The ATI crankshaft damper suited for Chevy small-block and 90-degree V6 applications is a 7.074in steel, three-ring harmonic balancer with part cues for Pontiac four-cylinder fitments. Provided as a single-piece damper, it controls crankshaft vibration and matches factory three-ring pulley arrangements for a range of small-block Chevy and related V6 engine swaps and rebuilds.
